Abstract

Two rhabdomesonid cryptostome bryozoans, Rhabdomeson progracile n. sp. and Rhabdomeson rhombiferum (Phillips, 1836), are described from the Lower Carboniferous of the British Isles. A revised familial diagnosis of Rhabdomesidae Vine, 1884, and a revised generic diagnosis of Rhabdomeson Young and Young, 1874, are presented. Taxonomic complications relating to the type species of the genus, which date from 1844, are discussed, and it is suggested that a new type species is required.
